as well. In pumping oil either in a pipe line or from a. well, the pil carries a certain percentage of water, whichv with the oil is in the form of. an emulsion. Crude oil from various wells has different percentages of water in it, and if desired to pump the oil from a number of wells or a slngle well into a storage tank, it is frequently desirable that the content of water which is with the oilbe known, so that the water which may settle 'out from the oil while in the storage tank may be determined.

It is an object of this invention to provlde a pipe line sampler which is adapted to take a true representative sample of the fluid in a pipe line and remove it from the pipe line without interfering or interrupting the flow through the pipe line.

With the foregoing and other objects in view which will be made manifest in the following detailed description and pointed out in the appended claims, reference is had to the accompanying drawings for an illustrative embodiment of the invention, wherein:

Figure 1 is a vertical section through the improved pipe line sampler shown as applied to a pipe line;

Fi 2 is a horizontal sectiontaken sub-- stant ally on the line 22 of Fig. 1;

Fig. 3 is a vertical section taken on th line 3-3 of Fig. 1;

Fig. 4 is an end elevation of the'pipe line sampler; and

Fig. 5 is a plan view, parts being broken away, showing 'a detail of constructionin a-modified form of invention.

Referring to the accompanying drawings wherein similar'reference characters designate similar parts throughout, the improved pipe line sampler consists of a body 10 r whichmay have its ends hexagonal in form,

indicated at 11 and 12 respectively, which"- ends are interiorly threaded, as at 13 and 14 respectively, to receive the ends of pipe sections 15 and 16 respectively, constituting a part of the pipe line. The top of the body 10 has an aperture 17 formed therein and one side wall of the body 10 is preferablybulged out, as indicated at 18. A web 19 extends from the bottom of, the body 10 to the top of the body. This web is preferably arcuate in form so asto provide arcuate surfaces 20 and cooperates with the bulged outside wall 18 to form a by-pass 21. The aperture 17 formed in the top of the body is preferably disposed over the opening formedbetween the web 19 and a sidewall 22. The side wall 22 presents an arcuate surface 23 and is so positioned as to form openings 24 between the ends of the arcuate web 19 and the side Wall 22.

'Within the opening between the web 19 and the side wall 22 there is disposed a movable or rotatable member 25, preferably cylindrical in form and having its sides bearing upon the arcuate surfaces 20 and 23. A stem .26 is formed integral with the rotatable member 25 and extends upwardly through the aperture 17 formed in the top of the body 10. Upon the top of the rotatable member 25, there is placed a washer 27,

upon which rests packing 28, preferably rubber, and a gland member 29 is disposed about thestem 26 and is adapted to com-- end of the stem 26 is squared, as indicated at 33, to receive a wrench or handle-34, which is maintained in place by means of a nut 35. By means of the handle 34, the rotatable member 25 may be rotated. An opening 36 is formed in the rotatable memgland member 29 has apertures 30 tightened towards the body 10. The upper" ber 25 and extends diametrically therethrough. This opening is preferably in height equal to the internal dlameter of the pipes 15 and 16. Adjacent the bottom of the opening 36 there is formed a web- 37 extending across the opening and an aperture 38 is formed through this web. In the bottom of the body 10 there are preferably lio . provided two. apertures 39 which receive the threaded ends of tubes 40. The apertures 39 are arranged upon diametrically opposite sides of the center of the rotatable member 25, as clearly shown in Fig. 2. An aperture 41 is formed in .the side wall 22 of the body 10 and is so located as to be in the same vertical plane which includes the apertures 39. A suitable nipple 42 is threaded into the aperture 41. V

The operation of-the device is as follows: Oil, which has water mixedtherewith or other fluid, continually passes through the pipe line which includes the pipes 16 and 15. The fluid which enters the pipe line sampler from the pipe section 16 may readily pass through the by-pass 21 formed between the web 19 and the side wall 18. When the rotatable member 25 is in that position shown in Fig. 2, a part of the fluid in the pipe line may also readily passthrough the opening 36. I When it is desired to take-a sam le of the fluid passing through the line,

' that t of the the andle or wrench 34 is swung around, therebg rotating the rotatable member 25, so

by the arouate surfaces 20 and'23. In this manner, the fluid which was passing throu h' the opening 36. is entrapped therein. T e

rotation of the rotatable member 25 is continued until the bottom of the opening 36 is directly above the apertures 39. At the same time one end of the opening 36 will be caused to be positioned opposite the a erture 41. The uid which is entrappe in the o ening 36 ma then readily pass downward y through t e tubes 40 in the apertures 39. That portion of the fluid which is above the web 37 passes through the web through the aperture 38. The nipple 42 provi es a vent forthe opening 36 so that the fluid which is entrapped therein may readily pass downwardly through the tubes 40. It will'be readily understood that while the sample is being. taken, the flow of fluid through the by-pass 21 is in no way interfered with or interrupted.

In some. cases the water which is in the fluid in the pipe line because of the fact that it is heavier than 011, will tend to settle to the bottom of the pipe line while flowing therethrough; but having the height of the opening 36 equal to the internal diameter of the pi e line, a true representative sample uid in the pipe line can be obtained, as the opening 36 will then entrap a proportionate amount of water in the bottom of the pipe line together with a proportionateamount of oilwhich is at the top tha pipe line.

e purpose of providing the web 37 isto keep the halves of the rotatablemember 25, wh1ch are formed by the opening 36, in

proper spaced relation to each other. This webwill prevent the halves from collapsing eends of the opening 36 are closed terrupting the flow therethrough.

ratchetwrench there is a toothed ring 43" I which is adapted to be placed upon the squared portion 33 of the stem 26. The ratchet handle 44 is provided with apawl 45 disposed within a bore 46 and about which there is arranged a coil spring 47, which urges the pawl 45 into engagement with the teeth. The end of the handle 44 is preferably connected by a suitable link mechanism to the polish rod or other re-' moving device which operates the well pump. In this manner every stroke-of the polish rod will cause the ring 43 to be advanced the distance or one teeth, and sam ples of the fluid delivered from the well can in this manner be obtained automatically at regular intervals.

When the sample is obtained from the pipe line sampler, it may be taken to a laboratory and analyzed to determine the exactcontent of the various substances. forming the fluid.

It will be understood that various changes in the detail of construction may be made for taking. and removing a representative sample of fluid in the pipe line without in- 2. A pipe line sampler comprising a body,
